But the T-Mobile Arena didn’t sell out instantly as many expected it to. In fact, there were huge swathes of seats empty on fight night, probably because average fans couldn’t afford the $2,500 it cost for mere nosebleeds. One man who was there to see it live was UK McGregor fan Oliver Regis, who picked himself up one of those aforementioned upper bowl tickets. But after noticing all the empty seats down on the floor, he decided to see how close he could bluff his way to the ring.

He ended up in the third row surrounded by celebrities like Jamie Foxx and Jennifer Lopez. The ticket prices for seats in that area? A cool $25,000.

“I did feel a bit cheeky, but this was a once-in-a-lifetime chance,” Regis told The Sun. “I could not believe it worked. There were quite a few empty seats. I sat down in the third row and Mike Tyson then sat down behind me. LeBron James was on my row and I could see Leonardo DiCaprio.”

Regis pulled off upgrade by walking onto the floor with a contingent of Floyd Mayweather’s security team. Staff assumed he was with them and didn’t even bother to scan his ticket. The hardcore McGregor fan (he’s got a Notorious-inspired tattoo on his leg) spent the rest of the evening hobnobbing with A-list celebrities and getting selfies with people like Mike Tyson, Dana White, Gerard Butler, Jeremy Piven, P Diddy, Demi Lovato, and Chris Hemsworth.

That’s one way to get your money’s worth out of an expensive Mayweather vs. McGregor ticket!
